-as mentioned likely a VR issue -is it the original AUTO-LITE unit -see picture below. Belt tension too can affect that. Is AMMETER original induction style? By 'registering more '+' positive' -like more than 10 AMPS? You say after reconnecting the battery and restarting/shutting down engine, the spinning stopped, was OK except the '+' ammeter. When you flip on the headlight switch, does the ammeter show any change? It should show a '0' or NEG (-) reading. It shouldn't matter but can try to polarize generator next time you disconnect/reconnect battery cable before starting up.
